-' MACHINE FOR EMPTYING BARRELS.

Specification of Letters Patent.

Patented July 27, 1920.

Application filed September 22. 1919. Serial No. 325,457.

To all whom it may concern:

Be it known that I, CLIFFORD C. Mosrrnn, a citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have invented new and useful Improvements in Machines for Emptying Barrels, of which the following is a specification.

My invention relates to machines for re moving the contents from containers, without comminuting the same when the substance contained therein is neither a solid nor a liquid but a semi-solid, viscous substance, which has to be scooped out. My machine is particularly designed and adapted for removing lard from barrels and will be specifically described hereinafter and illustrated in the drawing as a lard barrel emptier, although, as will be obvious, it may be used to remove other similar substances from cans, or other recep-v tacles.

In the accompanying drawing,

Figure 1 is a perspective view of the machine in use,

Fig. 2 is a detail of one part of the mech anism.

Fig. 3 is a side view of the cutter head, and

Fig. 1 is an end view of the same.

The apparatus comprises standards 1 and 2, mounted on the floor or other suitable support, and a base or cradle 3 for the barrel 4 to be emptied. 5 represents a chute to receive the lard as it comes from the barrel and, as shown, said chute passes through the floor to a suitable receptacle, not shown.

A shaft 6 is journaled in the standards 1 and 2 so as to be freely movable longitudinally therein, and the front portion of said shaft is screw-threaded as shown at 7 Standard 2 contains a lever 8, pivoted therein at 9, and carrying a half-nut 10, adapted to engage the screw-thread 7 on the shaft. The free end of the lever 8 projects through a slot in the front of the standard 2, see Fig. 2, terminating in a hand grip 11, below which is a pivoted pawl lever 12, adapted to engage serratlons or teeth 13, formed on the standard. By means of said levers, the nut 10 can be engaged with, or disengaged from the screw.

Shaft 6 carries a gear 14: fast thereon, and with said gear meshes a pinion 15, slidably keyed on the countershaft 16, journaled on the standards. Said pinion is kept in mesh with said gear by means of brackets 17, secured to shaft 6 one on each side of gear 14:. Countershaft 16 carries a gear 18 outside of standard 1, which gear is driven by a pinion 18', the shaft of which is journaled in the standard 1 and which is driven by a crank 19, or from a motor, not shown.

On the front end of shaft 6. is mounted the cutter head 20, which consists of a disk slit radially along a diametral line on opposite sides of the hub 26, and having one of the edges 25 on each side of said hub bent out of the plane of the disk so as to form each half of the disk into a spiral or scoop-shaped blade, approximately of the diameter of the inside of the barrel to be emptied and of a suitable shape to cut through the lard as the shaft is rotated and fed forward.

On the outside face of standard 1 is journaled a winding drum 21, the shaft of which is provided with a crank 22. Cords 23 run from said drum, through the stand ard 1, to the collar 24 on the shaft 6, which collar may carry one of the brackets 17,-

hereinbefore described.

The manner of use of the apparatus is as follows:

The barrel, with one head removed, is laid on the cradle 3, the shaft 6 being retracted so that the gear 141 is close to the standard 1. The nut 10 is put in engagement with the screw 7, and the shaft 6 is rotated by the crank 19. This feeds the cutter head into the barrel, the blades cutting through the lard until the desired depth is reached. Then the nut is disengaged from the screw and the drum 21 is rotated to pull the shaft out of the barrel, the head 20 bringing with it the lard through which it has been passed, the lard, as it issues from the barrel, falling into the chute 5.

It will be apparent that the invention is not limited to the exact form of mechanism described, as some of the details may be varied without departing from the principle of the invention, as expressed in the following claims:

What I claim is 1. A device for the purpose described,

comprising the combination of a cradle to ranged to be engaged with or disengaged from the screw-thread on said shaft, a cut ter head, having scoop-shaped blades on the end of said shaft, and means to retract said shaft and head bodily When said half-nut is disengaged from the shaft.

2. A device for the purpose described, comprising the combination of a cradle for a container to be emptied, two spaced standards in front of said support, a shaft journaled in said standards andmovable 1ongitudinally therein, a cutter head on the end ofsaid shaft, a half-nut on one of said standards, means to put said half-nut in engagement with a screw-thread on said shaft and to hold it out of engagement therewith, a gear fast on said shaft and movable therewith, a countershaft on said standards, a pinion slidably keyed on said counter-shaft, means to keep said pinion in mesh With said gear, means to rotate said countershaft, a drum journaled on the standard farthest from said support, means to rotate said drum, and a cord Wound on said drum and having its free end attached to said shaft.

In testimony whereof I have hereunto set my hand.

CLIFFORD C; MOSHER.
